Most sprained ankles heal fully with home treatment, but the key is matching your approach to the severity of the injury. A mild sprain typically takes one to two weeks to heal, while a complete ligament tear can take several months, especially if surgery is needed. What you do in the first few days, and how you rebuild strength afterward, has a major impact on how quickly you recover and whether the ankle stays healthy long-term.
Figure Out How Severe Your Sprain Is
Ankle sprains are classified into three grades based on how much damage the ligaments sustained. Understanding your grade helps you set realistic expectations and avoid pushing too hard too soon.
A Grade 1 sprain means the ligament is stretched or slightly torn. You’ll notice mild tenderness, some swelling, and stiffness, but the ankle feels stable and you can usually walk with minimal pain. A Grade 2 sprain involves a more significant but still incomplete tear. Expect moderate pain, noticeable swelling and bruising, tenderness to the touch, and pain when walking. A Grade 3 sprain is a complete tear of one or more ligaments. Swelling and bruising are severe, the ankle feels unstable or “gives out,” and walking is likely not possible.
If you can’t put weight on the ankle at all, or if you feel tenderness directly over the bony bumps on either side of the ankle, you may need an X-ray to rule out a fracture. These are the criteria emergency doctors use to decide whether imaging is necessary.
What to Do in the First 48 to 72 Hours
The traditional advice for a fresh sprain has been RICE: rest, ice, compression, and elevation. That’s still a reasonable starting point, but sports medicine has shifted toward a newer framework called POLICE: protection, optimal loading, ice, compression, and elevation. The difference comes down to “rest” versus “optimal loading.”
Prolonged rest, it turns out, can actually slow recovery. Extended immobility produces adverse changes in tissue strength and structure. Instead of staying completely off the ankle for days, the goal is to protect it from further injury while introducing gentle, controlled movement as early as you can tolerate it. That might mean light ankle circles or partial weight-bearing with crutches within the first day or two, depending on pain levels.
For ice, apply it for 15 to 20 minutes at a time, with a barrier between the ice and your skin, several times a day. Compression with an elastic bandage helps control swelling, and keeping the ankle elevated above heart level whenever you’re sitting or lying down encourages fluid drainage.
Be Cautious With Pain Medication
Anti-inflammatory painkillers like ibuprofen are a natural reach when your ankle is throbbing, but there’s a catch. Inflammation is part of the healing process, and suppressing it too aggressively in the first few days may interfere with ligament repair.
In one study comparing patients who took anti-inflammatories versus a placebo after ankle sprains, the medicated group had significantly greater ankle instability at days 3, 7, and 14. They also had less range of motion at 7 and 14 days. The likely explanation: reduced pain encouraged them to resume activity before the ligament was ready, which increased swelling and loosened the joint further.
If you do use these medications, keep the duration as short as possible and don’t let the pain relief trick you into overdoing it. Acetaminophen (Tylenol) is an alternative that manages pain without directly affecting inflammation.
Rebuilding Range of Motion
Once the worst of the swelling subsides, usually within a few days for mild sprains, you can begin working on restoring movement. Stiffness is normal, and the ankle will feel tight. These exercises are gentle enough for early recovery:
- Alphabet writing: Sit with your foot off the floor and use your big toe to trace each letter of the alphabet in the air. This moves the ankle through its full range in every direction.
- Towel stretch: Sit with your leg straight, loop a towel around the ball of your foot, and gently pull it toward you to stretch the calf and heel cord.
- Golf ball roll: While seated, roll a golf ball under the arch of your foot for about two minutes. This loosens the connective tissue along the bottom of the foot, which often tightens up after a sprain.
Aim for 3 to 5 sessions per week. The goal isn’t to push through sharp pain. If a movement hurts, ease up and try again the next day.
Strengthening the Ankle
Once you can move the ankle through its full range without significant pain, it’s time to start rebuilding strength. Ligament injuries weaken the surrounding muscles, and those muscles are what keep your ankle stable during everyday activities.
- Resistance band exercises: Sit with your leg extended and wrap an elastic band around the ball of your foot. Pull your toes toward you against the band’s resistance (working the front of the shin), then point them away (working the calf). You can also angle the band to work the ankle inward and outward.
- Calf raises: Stand and slowly rise onto your toes, then lower back down. Start with both feet, and once that feels easy, progress to single-leg raises on the injured side.
- Towel curls and marble pickups: Place a towel on the floor and use your toes to scrunch it toward you, or pick up marbles one at a time with your toes. These target the small muscles in the foot that contribute to overall stability.
Balance Training Is the Most Important Step
This is the part most people skip, and it’s the part that matters most for preventing re-injury. When you sprain your ankle, you don’t just damage the ligament. You also disrupt the nerve signals that tell your brain where your foot is in space. This is called proprioception, and without retraining it, the ankle remains vulnerable.
A meta-analysis of studies on proprioceptive training found that it reduces the risk of future ankle sprains by about 35%. For people who’ve already had a sprain, the risk reduction was 36%. These are significant numbers for something that takes only a few minutes a day.
The simplest exercise is the single-leg stand. Stand on your injured foot and lift the other foot off the ground. Try to hold for 30 seconds. At first, you may need to touch a wall or counter for support. As you improve, try it with your eyes closed, on a pillow, or while gently tossing a ball from hand to hand. The instability forces your ankle’s stabilizing reflexes to rebuild.
Up to 40% of people with lateral ankle sprains go on to develop chronic ankle instability, a condition where the ankle continues to give way and can eventually lead to arthritis. Balance training is the single most effective tool for avoiding that outcome.
Bracing and Support During Recovery
As you return to activity, external support helps protect the healing ligament. Both athletic tape and semi-rigid ankle braces are commonly used, and research has not conclusively shown one to be superior. In a pilot study of young soccer players, those who used an adaptive brace returned to sport in a median of 52.5 days compared to 79.5 days in the control group, though the difference wasn’t statistically significant given the small sample size.
From a practical standpoint, braces are easier to apply yourself, maintain their support throughout the day, and are reusable. Athletic tape loosens with sweat and movement and requires someone skilled to apply it properly. For most people returning to exercise or sport after a sprain, a lace-up or semi-rigid brace is the more realistic choice.
Recovery Timelines by Severity
Grade 1 sprains typically heal in one to two weeks, and you can often return to normal activities within that window as long as you’ve regained full range of motion and can walk without pain. Grade 2 sprains generally take four to six weeks, with a more gradual return to sport or high-demand activity. Grade 3 sprains require the longest recovery, often several months, and some may require surgery if the ankle remains unstable after a full course of rehabilitation.
Surgery is typically considered only for chronic instability that hasn’t responded to bracing and physical therapy, not for fresh injuries. The vast majority of ankle sprains, even severe ones, heal well with consistent rehabilitation. The deciding factor in long-term outcomes is rarely the initial severity of the tear. It’s whether you follow through on strengthening and balance work in the weeks and months after the pain fades.
